A mobile exit is shared with thousands of real subscribers, which is what makes it hard to block. How dedicated LTE ports differ from pooled bandwidth.

A mobile proxy is not a residential proxy with better marketing. The difference is structural, and it comes down to one piece of carrier architecture: the address you exit from was never yours to begin with.
Mobile operators have far more subscribers than IPv4 addresses, and the fix is carrier-grade NAT. Hundreds or thousands of handsets share one public address, and the carrier tracks which internal session owns which port. A commuter on Vodafone in Manchester and a modem in the same city present the same IP to the same website.
That is the entire argument for mobile. Blocking a datacenter address costs a site nothing. Blocking a mobile address also blocks every real customer behind that NAT pool, and the site has no way to separate them. At that point the block is a commercial decision rather than a technical one, and most sites decline to make it.
It also explains why mobile addresses recover on their own. A flagged residential IP tends to stay flagged, because the reputation attaches to one household. A CGNAT address is continuously re-used by ordinary traffic, so its reputation is dragged back toward neutral whether or not you change anything.
FleetProxy sells mobile in two shapes, and they suit different work.
Mobile LTE is a dedicated modem port — a real SIM in a real handset modem — at $1.60 per IP per day, falling to $0.96 at 90 ports. Data is unmetered. You are reserving hardware, so the cost is time-based.
Rotating mobile is the same carrier estate pooled and metered, at $3.40 per GB down to $2.04 at 250 GB. Nothing is reserved, rotation is per request by default, and a session can be pinned for up to 60 minutes.
The arithmetic decides it. A dedicated port costs $1.60 a day whether you push 50 MB or 50 GB through it. Against $3.40 per GB, the pooled product is cheaper below roughly half a gigabyte per port-day and more expensive above it. A two-hour campaign should not reserve a modem for a week. An account-warming routine that needs the same carrier address every morning should not be metered.
On a dedicated port you trigger rotation and the carrier returns a new address in about 12 seconds. That is a PDP context being torn down and re-established, which is why it is seconds rather than instant:
curl -s https://api.fleetproxy.com/v1/proxies/px_4nc77bt/rotate \
-H "Authorization: Bearer $FLEETPROXY_API_KEY" \
-X POSTYou can also set an automatic interval between 5 and 60 minutes and never call the endpoint.
The timer is the part people get wrong. A five-minute rotation applied to a login flow that takes seven minutes will change the address mid-session and cost you the account you were trying to protect. Set the interval longer than your longest logical unit of work, or rotate explicitly when that unit finishes.
Country selection is table stakes. Operator selection matters when the target treats networks differently, which is common in ad delivery because inventory is frequently bought per carrier.
curl -x http://user-country-us-asn-21928:[email protected]:8080 \
https://api.fleetproxy.com/v1/ipAS21928 is T-Mobile US. On the pooled product, ASN targeting reaches individual operators across 60+ carriers in 38 countries; on a dedicated port the carrier is chosen at checkout and the ASN is fixed for the lease.
Targeting narrows the pool, and narrowing it too far is the commonest self-inflicted failure. One operator in one country is a much smaller set of exits than one country, which raises the request rate per address and produces exactly the pattern rate limiters watch for.
Speed. Radio scheduling and NAT translation both add latency, and mobile is the slowest exit class in the catalogue. For comparison, rotating datacenter runs a 0.28s median response and rotating residential around 0.7s to first byte. On a job doing a few thousand requests that difference does not matter. On one doing ten million it decides whether the run finishes overnight.
Price is the other cost. At $3.40 per GB, pooled mobile is roughly triple rotating datacenter's $1.20 and well above residential's $2.65.
So mobile is an escalation tier, not a default. Start on rotating datacenter, move to rotating residential when reputation is what is blocking you, and reach for mobile when residential is being blocked too. Paying mobile rates for a target that never checks ASN reputation is the most common way to overspend on proxies.
| Workload | Product | Why |
|---|---|---|
| Account creation and warm-up | Mobile LTE | One address held for days, unmetered |
| Mobile ad verification | Rotating mobile | Many carriers, short bursts, per-GB billing |
| App store and mobile SERP checks | Rotating mobile | High request count, low bytes per request |
| Long-lived logged-in sessions | Mobile LTE | The address must not change under the session |
| Fraud and traffic research | Rotating mobile | Breadth of carriers matters more than tenure |
aiohttp handles proxies differently from requests, and the differences fail silently: SOCKS5 connectors, timeouts, and pooling that breaks rotation.
A 407 means the proxy refused your credentials, and there are exactly six reasons it does that. Here is how to tell them apart in under a minute.
